IMPROVEMENT IN PLOW-COLTERS.

Specication forming part of Letters Patent No. 126,655, dated May 14,1872.

T o 'whom it 'may concern: Be it known that I, BEERI W. TUTLn, ofGalena, in the county of J o Daviess and State of Illinois, haveinvented a new and useful Improvement in Plow-Oolters; and I do declarethat the following is a true and accurate deaccompanying drawing and tothe letters of reference marked thereon and being a part of thisspecification, in which- Figure 1 is an elevation of my improvedrocross-section, a modification ofthe same.

Like letters indicate like parts in each figure. The nature of thisinvention relates to an ters for plowsg. and it consists in the peculiarconstruction and conformation of the colter, which is plano-convex insection, with the convexity toward the land of the furrow, andconstructed with plano-convex segments bolted to a dat disk, whichsegments may be easily and cheaply renewed when worn.

In the drawing, A represents the colterwheel shaft, which may bejournaled in any convenient manner to the plow-beam. This shaft isturned down to receive a hub, B, and

threaded, as at c, on which to screw a collar,

C.' Between the hub and collar the colter D is received, and secured onthe shaft by screwing up the collar. The colter-Wheel is so disposed onthe shaft as to present its convex side to land, and thus prevent theplow from running in, and greatly relieves the plowman in the labor ofguiding the implement. As the colter-wheels rapidly wear out, from theexcessive abrasion to which they are subjected by rolling in contactwith the soil and cutting the sod, if molded or forged solid, and thusrendering renewals expensive, I make the wheel in the form of a thindisk, about the perimeter of which, on one face, I secure planoconveXsegments D with countersunk bolts, as shown at b, Fig. 2.

What I claim as my invention, and desire to secure by Letters Patent,is-

A colter-wheel, composed of a disk, D, having the plano-convex segmentsDl secured thereto by the countersunk bolts b, substantially asdescribed.
